Remember the “twisting neck” scene from 1973’s Exorcist movie? The “Exorcist illusion” provides a similarly creepy effect. It is a variation of the hollow-face illusion. Although there are no moving parts on the construction, it appears that the torso and face rotate in opposite directions. Watch the following video and see for yourself.

This illusion was created by Thomas Papathomas, Tom Grace Sr., Marcel de Heer and Robert Bunkin at Rutgers University. It was a finalist for the 2012 Best Illusion of the Year Contest.
